NOTES AND EXHIBITS. 503 



lalmenus myrsilus, Doubl., bred by Mr. Lyell. Also, for Mr. 

 Maiden, a bunch of curious horn-like galls (Fam. Cynipicke) upon 

 the twig of a Eucalypt. 



Mr. R. T. Baker exhibited specimens of a Morell, Morchella 

 conica, Pers., from Moonbi Plains, Tamworth, N.S.W., found by 

 Mr. D. A. Porter: also a fossil leaf and some fossil wood from 

 Wyrallah, Richmond River; the venation of the leaf is beautifully 

 preserved, its characters being highly suggestive of Eucalyptus. 



Mr. T. Whitelegge exhibited a rare and curious Isopod, 

 Amphoroidea australiensis, originally described from N.S. Wales 

 by Dana in 1852, since when it appears to have escaped notice. 

 The specimen exhibited was obtained on seaweed at Maroubra 

 Bay last June; when alive it was bright olive-green, and of a 

 similar tint to the seaweed to which it was adhering. 



Baron von Mueller contributed the following 



J^otes mi Boronia floribunda, Sieher. 



In the earlier jDart of this century (during 1823) the Bohemian 

 botanist, Franz Wilhelm tSieljer, formed extensive collections of 

 herbarium plants in the vicinity of Port Jackson and on the Blue 

 Mountains; and although his stay in Australia lasted only seven 

 mouths, and was limited to N.8. Wales, he extended largely our 

 knowledge of the indigenous flora there, more particularly through 

 the distribution of typic specimens, quoted in De CandoUe's 

 Prodromus and in other descriptive works. These records have 

 had significance up to the present day, as will Ije instanced by 

 one of Sieljer's Boronias, namely, B. floribunda, which Professor 

 Ignatius Urban, of Berlin, some few years ago, on a re-examina- 

 tion of this plant in Sieber's published set, restored to an 

 independent specific position, Bentham in the Flora Australiensis 

 having regarded it as having arisen from dimorphism. Authentic 

 specimens from Sieber were not available in Melbourne when the 

 first volume of the Flora became elaborated, and thus B. flori- 

 bunda remained to be considered a mere state of B. jnnnata, until 

 the distinguished Berlin phytographer opened up this question
